ITE STATES LORENZ A. DEUTHER, OF BUFFALO, NEW YORK.

SPECIFICATION forming" part of Letters Patent N 0. 689,466, dated December 24, 1901. Application filed May 17, 1900. Serial No. 17,042. tllo model.)

To all whom it may concern.-

Be it'known that I, LORENZ A. DEUTHER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Machines for Making Picture-Backboards and the Like, of which the following is a specification.

My invention relates to a machine for making laminated boards in which a plurality of slats of wood or other suitable material are cemented between two sheets of paper or other flexible material; and the object is to produce a machine having mechanism for feeding the slats, mechanism for coating the paper or other flexible material with cement, and mechanism for assembling the slats between the coated sheets.

For a full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description.

The invention is susceptible to various changes in the form, proportion, and minor details of construction without departing from,

tages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which- Figure 1 is a side elevation of my improved machine. Fig. 2 is an enlarged side eleva-' tion of the forward part of the machine with the operatingearing removed. Fig. 3 is a vertical longitudinal section on or about line Ct at, Fig. 4:. Fig. 4 is a top plan view with the slat-receiving rolls and belts removed. Fig. 5 is a detail view of one of the guides employed for retaining the slats in a horizontal position.

Referring to the drawings in detail,like numerals designate like parts.

The frame 1 of the machine is provided with hangers 2 and 3, in which shafts'of several of the operating parts are journaled. The shaft 4 is journaled in the boxes 5 in the lower portion of the hangers 2 and may be adjusted vertically by means of the adjusting-screws 6. Shafts 7 and 8, carrying pulleys 9, are journaled in the upper portions of the hangers. Vertical supports or frame-pieces 10 are arranged on each side of the pulley =9 and are provided with forked lower ends, which fit over the horizontal cross-bars 11 and 12,thereby holding the supports or frame-pieces in vertical position. Adjustable pulleys 13 are journaled in the upper portions of the supports or frame-pieces and are operatively connected with the pulleys 9 by the endless belts 14. The upper pulleys 13 are vertically adjusted to tighten the belts by the adjusting screws 15.

Two sets of the upper and lower adjustingpulleys are preferably employed and the slats are arranged between the belts that they carry, and fed vertically downward.

A means is provided for maintaining the ends of the slats in alinement, which preferably consists of two vertical arms 16, which extend upward from the frame on each side of the belts and pulleys and in the same vertical plane as the space between the belts.

Vertical stops or standards 17, having horizontal pins 20 adjustably fitting in openings in enlargements 21 of the arms 16, serve as alining-stops for the slats and are adapted to be adjusted toward or from each other to receive different lengths of slats.

The pins 20 are secured in their adjusted position in the enlargements 21 by the setscrews 22.

Toothed feeding-wheels 23 are mounted upon the horizontal shaft 24, journaled in the frame, and take the slats as they come from the vertical belt-feeding mechanism and feed them upon the horizontal table or top 25 of the machine-frame. As the toothed wheels 23 are revolved in the direction indicated by the arrow the slat is carried from under the stack and is pushed between the guides 26 and 27, the lower guides 26 running parallel with the machine, forming a bed which receives the slats from the stack as they are successively fed to it by the toothed wheel 23 and the adjustable guides 27, which are secured to the cross-rods 1.1 and 29 and are rigidly held in place by the nuts 30, just suiticient space being left between the guides 26 and guides 27 to permit the slats to pass loosely between them, as shown in the drawings. As the slats are carried from the stack and between the guides 26 and 27 they pass between the feed-wheels 31 and 32, mounted in the hangers 3. As many of these wheels 31 and 32 may be used as desired, and these are mounted parallel with the slats passing between them, and as they engage each slat they force it forward to the depression or cementing rollers 33 and 34. These depression or cementing rollers 33 and 34 are mounted directly o er each other, similar to the feeding-wheels 31 and 32, and the paper sheets 35 and 36, which are to be glued to the slats, are fed to the machine over these rollers 33 and 34, the pressure-rollers causing the paper to firmly adhere to the slats.

Referring to Fig. 1, 37 represents reservoirs for holding the liquid glue, in which are mounted the supply-rollers 38.

lhe paper sheets 35 and 36 are preferably supported in roll form upon spools 39 and are coated with glue or other cement as they pass over the coating or supply rollers 38, being held in contact with the supply-rollers by the rubber strip 41, which is mounted in the support 42, (see Fig. 1,) from whence the paper passes over guide-rollers 43, as seen in the drawings, and to the depression or cementing rollers 33 and 3%.

The slats are first fed vertically into the machine between the belts 14, as above described, and stacked over the toothed feedtug-wheels 23, where they are successively carried between the guides 26 and 27 and passing between the feed-wheels 31 and 32, where they are forced forward to the depression or cementing rollers 33 and 3s. These rollers 33 and 34, over which the glued paper passes, are loosely mounted in the hangers 3 and are caused to revolve by the passage of the slats between them, thus causing the slats to press closely against each other as they are forced along by the wheels 31 and 32, and the glued paper sheets 35 and 36, which are now pressed upon the slats as they pass between the rollers 33 and 34:, hold the slats firmly in place, thus'forming a stiff antiwarping backing.

I claim as my invention 1. A machine for making picturebackboards and the like, having feeding mechans ism, a toothed wheel for taking the slats as they come from said feeding mechanism, and means for pressing and cementing the slats between interposed cement-coated sheets of material.
